KOOTION 10 Pack 4GB Flash Drive 4gb USB 2.0 Flash Drives USB Drive Jump Drive Bulk Thumb Drive Swivel Memory Stick Black

At this price I really didnt expect quality from a 10pack of USB 3.0 drives. I expected a few to be defective and poor performance on the rest. However, every single drive passed a badblocks write test with no errors at all. Running basic benchmark showed what I would consider very usable performance. Benchmark numbers can vary wildly based on on setting but this was a favorable comparison to the more expensive drives I had on hand. Assuming they dont degrade later Im pleasantly surprised.

I bought these USB sticks because the were cheap and had a decent rating. I got less than what I paid for. While they are indeed 32GB capacity, they are absolute garbage. I knew something was wrong when the quick-format to NTFS took over 20 sec. I tried to write 10-15GB video files to these sticks. The write process took 10-15 sec to start then cycled: 16MB/s (3sec) --> 0MB/s (6sec) --> 16MB/s (3sec) --> 0MB/s (6sec) --> . . . . It did this through the whole write. Rather than throw them out, Ive tossed these aside and only use them when I need a give-away USB stick. Thats how Ill get rid of them.

Just what we needed

You will be sorry if you buy from this company. Over half of the USBs will not format correctly and have to be thrown away. Huge waste of time and expense. DO NOT BUY!!!!!

Works as expected. 2nd box I’ve bought

These are the perfect size for sharing files with friends inexpensively. After the first 10 were used I realized I want to continue to have them on hand anytime I want to share a file with friends and ordered 20 this time. What a deal.

Nice option for a low price way to pass pics or documents to another person. And they work.

I needed Low capacity drives for compatability with usb 2.0 devices. i tested these and yes these are fast usb 3.1 and have 16gb. Authentic -get what you pay for. i copied 16Gb at 20MB/s -reads at 120MB. fast read speeds to play 4k video from. photo of test results attached. good product for cheap affordable price and performance. although i hate the swing type handle. i knew what i was buying and i got exactly what was advertised.

Despite being sold as USB 3.0 flash drives, these flash drives are USB 2.0. My PCs and Macs see them as USB 2.0, data transfer is at USB 2.0 speed. They aren’t so expensive that I returned them, but if they work like USB 2.0 — they’re USB 2.0. If it looks like a duck, quacks like a duck…

I have a need to store a few ISO images for server build. This is a good value for a fast flash drive to install OS on servers for my home network. I have used 8 of them so far and they all work well installing OS to servers and computers. Not to worry about the reliability as this is just a portable way to install OS.
